Twin chain TT bike

Rollapaluza are teaming up with Tour de Ville for their next Kingspin event:

"Tour de Ville is a new bike shop unique in London, specialising in classic modern and pristine vintage frames, bikes and parts lovingly sourced. The shop is the culmination of over 2 years of preparation by owners former Dutch champion Jos van Veldhoven and Keith James (previously of Condor). Ten minutes from the city, Tour de Ville offer coffee and special events alongside their custom-build and repair services. "

All well and lovely. but buzzing through their site we found this beauty. What's with the double chain? Anyone? And Tony's already suggested that one side is fixed and the other freewheel Smile
